What is the mechanical advantage of a nail puller-similar to the one shown in the figure below-where you exert a force $$34\mathrm{cm}$$ from the pivot and the nail is $$1.1\mathrm{cm}$$ on the other side? What minimum force (in N) must you exert to apply a force of $$1220\mathrm{N}$$ to the nail? (Enter the magnitude.) $$\mathrm{N}$$
